Even with anti seize, once you torque them down hard, chances are the threads are locked. Not necessary a concern for something that is fastened down permanently, but for something that needs to be removable, stainless is to be avoided.

Speaking of thread lock. I personally like to use distorted thread locking nuts, I find they work a lot better than locking washers, nylon nuts, or threadlocker.

If you exceed the torque limit of a given fastener style/material/grade, it is always bad. SS fasteners using anti-seize, properly torqued, are not a problem to disassemble. I get it - you don't like stainless. It has it's place in the fastener world for sure, but it gets a bad rap when used improperly.

Every twenty minute job is a stripped thread away from being a three day ordeal.

If I wanted to make a stainless bolt and nut gall up I would do exactly what the chap in the video is doing Run it up and down dry at speed with an impact driver
Stainless steel has two characteristics that stand out that is not mentioned
It is a poor conductor of heat and has a high expansion rate when heated.
Stainless steel also wears out thread cutting tools quickly so poor manufacturing standards make for poor threads and also lead to galling
I have run my thumb and finger over some stainless threads and they are very rough Poor manufacture
Stainless steel fasteners of good manufacture and used correctly are fine in my experience Marine engineering and food factory maintenance

Ive used stainless bolts for ages in aluminum and to other SS hardware. I always use anti seize and have never had a galling problem.

Ive had more problems with old rusty iron or supposedly zinc bolts on my bikes.

Anytime Ive ever encountered a galling problem is because some hammer hands over tightened or cross threaded a SS bolt.

I agree SS gals easier, but In my experience its almost always caused by user error.

Galling is mostly a problem stainless into stainless. Also, it is important to buy fasteners from reputable vendors, not the chinesium junk from amazon, etc. My go to source for fasteners is mcmaster, they carry excellent quality products.

Great quality, pricier than most, but their delivery is as good as their quality. Sometimes the next day, never more than 2 or 3 days.

Yep, and they have CAD files for most of their products, which is super convenient.

Today I had my mechanic replace my stock brake system with the bike brake kit from RycaShawn. The mechanic said that OEM caliper bolts would not fit the treads in the new caliper, turns out they were stainless steel bolts, and the threads were damaged, so he had to buy new bolts.

Unless my previous mechanic put in stainless steel bolts when he was replacing my brake pads, for whatever reason.

But, stainless has 80% the strength of steel. I don't think the 'stainless' bolt would be damaging the threads of a steel plate.
